How soon can you start the clen? I am finishing off my cycle with primo right now, can I start the clen now? I am also going use hcg, then clomid at the end of my cycle (I don't want this to turn into "don't use hcg at the end of cycle" thread, I have done the research, and it is right for me), so can I take the clen while on hcg, then the clomid?
